Agilent 8453 Problem with a HP 89052B Sipper running different direction randomly

It appears that you’re experiencing an issue with your GMP Agilent 8453 UV-Vis system, specifically related to the HP 89052B Sipper running in the opposite direction during sequence runs.

Here are things you might consider investigating:

1. Communication Troubleshooting:

   • Ensure that the communication between the Agilent 8453 UV-Vis system and the HP 89052B Sipper is functioning correctly. Sometimes miscommunication can lead to unexpected behavior.
   • Check if the addresses are correctly set to use the default LAN card address.

2. Method Configuration:

   • Verify that the method settings in your Chemstation software are correctly configured. Double-check the direction specified in the method (clockwise or anti-clockwise).
   • Confirm that the correct method is being applied during your sequence runs.

3. Hardware and Connections:

   • Inspect the physical connections between the Agilent 8453 UV-Vis system and the HP 89052B Sipper. Loose connections or faulty cables could cause unexpected behavior.
   • Ensure that the sipper is securely attached and properly aligned.

"The on-screen sipper icon in Chemstation shows the correct direction of rotation." This makes me think it's a connection. Look for loose, faulty, corroded cables.

Thanks for the suggestion. The PC is down at the moment :(  It will take quite a while to have it fix, so couldn't try it but will keep you update
